城市轨道交通信号系统互联互通协议框架研究

Study on the Interconnection Protocol Framework for Urban Rail Transit Signal System

互联互通是城市轨道交通CBTC(基于通信的列车控制)信号系统的发展趋势。为了实现不同CBTC厂商系统设备间信息无缝融合,需要设计一种通用的互联互通框架协议,在满足安全可靠的前提下,兼容多个异构系统的互联互通的需求。从信息流的角度出发,将CBTC系统分为4种类型系统交互模式,探讨了信息交互中接口方式、通信体系结构、接口数据描述和应用信息的定义等4个核心问题的实现方式。结合重庆轨道交通互联互通示范工程,通过搭建交叉测试平台和仿真试验,验证了互联互通协议的通用性和可行性。

Interconnection and interoperability display the development trend of CBTC signaling system for urban rail transit in China.To achieve seamless integration of CBTC system information among different CBTC vendors,the design of a universal interconnection framework protocol is urgently needed to meet the requirements of security,reliability,and compatibility of heterogeneous systems.From the aspect of information flow,the system interaction modes in CBTC are divided into four types,and the implementation of the four core issues of interface mode,communication architecture,interface data description and application information definition in information interaction are discussed.According to the subway interconnection demonstration project in Chongqing City,and through the establishment of cross-test platform,the versatility and feasibility of the interconnection protocol are verified.
